ABSTRACT:
2-naphthyl phosphoramidites are readily and inexpensively prepared by the reaction of N-dichlorophosphinoamines with a 2-naphthol in an alkylamine. The 2-naphthyl phosphoramidites are stabilizers for polymers such as the polyolefins and enhance the stabilizing activity of hydroxyphenylalkyleneyl isocyanurates.
